Fig. 1 Electrostimulation of cavernous nerves (CN) at 12 wk. (a) Representative intracavernous pressure (ICP) recording of each experimental group. The black curve represents ICP values in response to CN stimulation. The red bar represents 50-s electrical stimulation of the CN. (b) The effect of stromal vascular fraction treatment in improving the ICP-to- mean arterial pressure ratio. ICP=intracavernous pressure; MAP=mean arterial pressure. * p<0.05 compared with vehicle group.

Fig. 2 Neuronal nitric oxide synthase (nNOS) staining in a penile midshaft specimen. Representative images of nNOS-positive fibers in penile dorsal nerve of each experimental group are presented. NNOS-positive fibers were stained red (arrow) in the dorsal nerve. Original magnification is ×400. nNOS=neuronal nitric oxide synthase; DAPI=4’,6-diamidino-2-phenylindole.

Fig. 3 Neurofilament (NF) staining in a penile midshaft specimen. Representative images are presented for NF-positive fibers in penile dorsal nerve of each experimental group. Original magnification is ×400. NF=neurofilament; DAPI=4’,6-diamidino-2-phenylindole.

Fig. 4 Masson's trichrome and phalloidin staining in a penile midshaft specimen. (a) Representative images of actin staining of each experimental group. Smooth muscle in corpus cavernosum was stained red. Original magnification is ×40. (b) Representative images of Masson's trichrome staining of each experimental group. Smooth muscle and connective tissue are stained red and green, respectively. Original magnification is ×40. DAPI=4’,6-diamidino-2-phenylindole.
